12.24 is the answer if you use 1MOA = 1"
11.69 is the answer if you use 1MOA = 1.0472"

This will depend on the maker of your scope.

Why would yardage be irrelevant, if a mil unit of measure is exponential at every 100yrds (3.6:100, 7.2:200, 14.4:300, etc) 3.4mil @ 100yrds is much smaller than 3.4mil @ 400 yrds, No?

You're getting inches, MOA, and MIL mixed up.
While the value in inches will vary by distance, the value of MOA per MIL will remain the same no matter the distance. IT IS THE VALUE OF INCHES PER MOA THAT CHANGES WITH DISTANCE. In your above example, "(3.6:100, 7.2:200, 14.4:300, etc)," it is wrong. The measurement is actually linear rather than exponential. Let's see if I could make sense of it using the same logic. This will assume 1MOA = 1"

No.

Mils and MOA are units of angular measurement, not distance.

1 Mil = roughly 3.6 MOA no matter what distance.
Now, the distance that 1 Mil or 1 MOA subtends is certainly different as range to target changes.

3.4 Mil at 100yds would subtend 12.8 inches at 100yds and it would subtend 51.4 inches at 400yds, but 3.4 Mil = 3.4 Mil no matter what the distance is.
Mils do not convert to inches without knowing the distance to target, but Mils equal Mils no matter the distance.

Randall has it correct. MIL to MOA relationship doesn't change over distance. 1 MIL will always = 3.438 MOA (True MOA, not Shooters MOA) whether it's at 1 foot or 1000 yard. Inches is a linear measurement and will increase in relation to MIL and MOA over distance.

Cool, thanks for the help guys!

There are 3.438 MOA per Mil. Therefore, 3.4 Mils X 3.438 MOA = 11.69.

I have noticed a few posts using the number 3.6. 3.6" represents the distance between the center of one mildot to the center of the next mildot at a distance of 100 yards.
